Description

STACKABLE CONCRETE FORMING APPARATUS COMPONENTS
Background of the Invention
[0001] The invention relates generally to concrete form apparatus and, more specifically, to components of concrete form systems, such as shore posts, that are configures to be stacked in neat and stable arrangements for compact shipping and orderly and safe stacks at work sites.
[0002] Concrete forming apparatus is in wide use in the construction of buildings, bridges, and other concrete structures. A common system for forming concrete structures uses a plurality of modular form components that are adapted to be assembled into a wide variety of configurations to conform to virtually any architectural requirement. Such forming apparatus components are typically made of metal so that they are strong enough to support the heavy weight of poured concrete and durable so that the components can be reused many times.
[0003] A common application of concrete forming apparatus is in the formation of elevated sections, such as floors or horizontal beams of a concrete building. Typically, pluralities of modular form panels are assembled to form the surface on which the concrete will be poured. These panels are supported on metal shore posts that typically are constructed of an inner tube that is received for telescopic movement inside an outer tube. Metal tubes achieve high load capacity and the telescoping tubes provide adjustment to various heights. The shore posts typically have a foot pad on the bottom end portion and an adaptable top element on the upper end portion used to releasably secure and support other components of the concrete forming apparatus.
[0004] After the new slab of fresh concrete has cured sufficiently, workers remove the shore posts and strip the formwork they supported. Commonly, the shore posts are reused at the project job site. Between uses, the shore posts are typically stored in an out of the way location. Because of the tubular shape of the shore posts, they do not stack one on top of the other, making it difficult or impossible to make a neat, orderly, compact or stable arrangement of the shore posts. The stacks or piles of shore posts are disorganized and unstable, and may form a safety risk to workers. Once the project is completed, the shore posts must be transported to a new project site. Again, the shape of the shore posts makes it difficult to band together in a stable, compact configuration for shipping and also makes it difficult to count for inventory purposes.
Summary of the Invention
[0005] The preferred embodiment of the present invention consists of a component of concrete forming apparatus having a longitudinal tubular element with top and bottom end elements that intermesh to allow the components to be stacked atop each other in a stable arrangement. In a preferred embodiment consisting of a shore post, the bottom end element is a foot pad or plate and the top end element is an adapter plate. The end plates distribute the load on the shore post and assist in connecting the shore post to other components of the concrete forming apparatus during placement of concrete. While the posts are stored between uses or during transport, the end plates function to provide a stable stack of the tubular shore posts.
[0006] In the preferred embodiment, the top end plate is a flat plate having a preselected width and the bottom end plate has a web section with a width slightly larger than the width of the top end plate and a pair of upturned flanges on either side of the web section. Accordingly, the top end plate of a shore post is received inside the flanges of the bottom end plate of an adjacent shore post. In addition, notches are formed in the perimeter of the end plates to provide a receptacle for the tubular elements of adjacent shore posts. In a stack of shore posts, the posts are arranged parallel to each other in an alternating top-for-bottom pattern. The round tubes of an upper shore post rest in the notches of the end plates of the next lower shore post and the side flanges of both bottom end plates keep the upper post from sliding or rolling off of the lower shore post. This provides the novel ability to stack multiple tubular components vertically in a column. The neatly stacked components are stable, easy to inspect, easy to count, compact, and easy to bundle for transport.
[0007] An object of the present invention is to provide round or tubular concrete forming apparatus components with end elements which cooperate to permit the components to be arranged in neat, stable, and compact stacks..
[0008] Another object of the present invention is to provide a shore post with top and bottom end plates that interact with adjacent shore posts to permit the shore posts to be arranged in neat, stable, and compact stacks.
[0009] A further object of the invention is to provide an arrangement of a plurality of concrete forming apparatus components such that stacks of the components at a job site are neat and stable, can be easily inspected and counted, and can be easily bundled together for transport
[0010] These and other objects will be understood by those skilled in the art upon a review of this specification, the associated figures and the appended claims.

[0012] Fig. 2 is a perspective view of a plurality of shore posts of Fig. 1 arranged in a stack.
[0013] Fig. 3 is an enlarged perspective view of a foot pad of a preferred embodiment of the present invention. [0014] Fig. 4 is an enlarged perspective view of a top end plate of a preferred embodiment of the present invention.
Detailed Description of Preferred Embodiments
[0015] Illustrated in Fig. 1, generally at 10, is a shore post representing a preferred embodiment of the present invention. The shore post 10 includes an outer telescoping tube 12, an inner telescoping tube 14, a bottom end plate or foot pad 16 and a top end plate or adapter plate 18. The shore post 10 may be telescopically adjusted in length between a foreshortened or collapsed position and an lengthened or extended position. The shore post 10 may be set at a plurality of adjusted lengths by use of a pin 20 that is inserted into a pair of diametrically opposed holes in the outer tube 12 and a selected pair of a plurality of holes 22 in the inner tube 14 spaced at a regular interval. Fine adjustment of the length of the shore post 10 is made by rotation of a threaded linkage member 24. Rotation of the linkage member 24 is facilitated by a pair of diametrically opposed handles 26 and 28 which extend radially from the linkage member 24.
[0016] The top end plate 18 is a flat plate of a preselected width and having a pair of notches 30 and 32 formed in opposing ends (Fig. 4). The notches 30,32 are preferably in the shape of a trapezoid. The corners of the trapezoid provide two contact points to the tubes of the post stacked above. The contact points are spread apart to provide a stable support to the above member The foot pad or bottom end plate 16 has a central web section 34 and an upturned flange 36, 38 formed on either side of the web section 34 (Fig. 3). The web section 34 is of a width slightly larger than the width of the top end plate 18. A pair on notches 40, 42 are formed in opposing ends of the web section 34 corresponding to the notches 30, 32 of the top end plate 18.
[0017] To arrange a plurality of shore posts 10 in a stack, a first shore post 1 Oa (Fig. 2) is placed on the floor or other supporting surface. A second shore post 1 Ob is oriented top-to-bottom relative to the first shore post 10a and placed on top of the first shore post 10a with the top end plate 18b adjacent the web section 34a and between the flanges 36a, 38a at one end and with the top end plate 18a adjacent the web section 34b and between the flanges 36b , 38b at the other end. Note that the outer tube 12b of the top shore post 10b rests in the notch 30a of the bottom shore post 10a, and similarly, the notch 32b of the top end plate 18 b of the top shore post 10b rests on the outer tube 12a of the bottom shore post 10a. The end plates 16a, 16a stably support the bottom shore post 10a and the flanges 36, 38 of each of the bottom end plates 16a, 16b prevent the top shore post 10b from rolling off of the bottom shore post 10a by limiting movement of the top end plates 18a, 18b. In this way, stable stacks of multiple shore posts can be created. In a preferred arrangement illustrated in Fig. 2, twenty-four shore posts are arranged in a stack six wide and four tall. Note that the handles 26, 28 have been adjusted at an angle relative to the stacked arrangement so as not to interfere with the tubes or handles of adjacent shore posts.
(0018] While the invention has been described with respect to a shore post as the preferred embodiment, the invention is applicable other tubular form components such as wall form pipe braces as well as to components formed of solid round bars, such as taper ties.
